Digital radio cameras (wireless television cameras) are beginning to be used in the BBC for making a wide range of television programmes. They have the advantage over analogue radio cameras in that they have a greater immunity to multipath and interference. This ruggedness comes from the use of the DVB-T (Digital Video Broadcasting - Terestrial) modulation standard developed for digital television. However, to maintain a high picture quality, while minimising video coding delay, a high bit rate is transmitted. Programme makers are experimenting with using digital radio cameras where analogue radio cameras would not normally be considered, such as in television studios. This expansion of use comes at a time when the 2.5GHz band will soon be reallocated to 3G mobile technology and so suitable alternative spectrum will be needed for digital radio cameras. The technology behind digital radio cameras is outlined, concentrating on the design compromises that have an impact on spectrum usage. Future trends in the development of digital radio cameras by the broadcast industry are also discussed. The various applications for digital radio cameras will be described indicating the numbers of cameras involved in order to indicate the spectrum requirements. Results from measurements carried out in collaboration with the RA and JFMG Ltd to assess the feasibility of sharing with unlicenced users in the 2.4GHz are outlined.
